What is the pressure in atmospheres?
Need help in starting it. Don't have a clue.

30000 molecules / 6.02X10^23 = 4.9834 * 10^-20
0.001 L
10 K
PV = nRT
P = 4.98*10^-20 * 8.31 * 10 / 0.001
P = 4.141 X 10^-15 Pa

Use PV = nRT, where P is the pressure (which you want), V is volume, n is the number of molecules or moles, R is the universal gas constant, and T is the absolute temperature (given). To do this, you need to use the gas constant in appropriate units; check your text to see what it gives you. Or spend $140 for a copy of ...

If there is a pressure, I can not understand it. I believe they are fee molecules. There is no pressure.
;-D The pressure is too small to be measured.

pV = nRT, p = nRT / V
thus p = (30,000/6.023)*10^-23 * 0.082 * 10 / 10^-3
p = 4.98 * 10^-20 * 0.082 * 10^-2
p = 4.08 * 10^-23 atm
